This invention relates to improvements in weather stripk attachments especially adapted for sealing the bottom of doors, although the same is equally applicable to other uses.`

The object of this invention is to improve and simplify the construction of weather strip attachments inwhich the weather strips `are adapted to be'withdrawninto the edge of the vdoor or other device to which they are applied when the same is open and to be projected therefrom into engagement with the iioor or sill when the door is closed. In devices ofthis character the weatherv strip is guided atits ends and is moved laterally bymeans of links, toggles or other connections which are secured to and operated by an actuator'. In most instances the Vactuator is located within a casing and hasa portion which projects beyond the edge of the door and is adapted to engage `with the door j amb as the door is closed. l Such engagement with the door jamb serves to move Vthe actuatorl longitudinally and to thereby act uponthe weather' strip to moveit laterally in the manner aforesaid.

A further object of this invention is to provide means whereby the movement of the actuator can be adjusted so that the sealing means will accommodate spaces of various heights.

A further object is to provide new and improved anti-friction means for guiding the movement of the sealing means.

With these and other objects in view as will hereinafter appear my invention consists in the construction, arrangement and combination of the various parts of my device, where* by the objects contemplated are attained, as

Y hereinafter more fully set forth, pointedvout Y in my claims and illustrated in the accompanying drawings, in which:

Figure 1 is a horizontal, cross section of my invention;

Figure 2 is a vertical, cross section of my 2 of Figure 3,

and

Figure 3 is an end elevation of a portion of the door. l s

In the drawings like reference characters refer to like parts.

Referring to the drawings 10 indicates a door generally and the door may be either an outside or an inside door. The door j amb is indicated at 11 having the bumper plate 12 v spring retaining member desired cast integrallyl with the plate 16.

through a slot 22 in the downwardly lng portion 21 is the actuator or slidable bar aitixedthereto by the screws 13 or any other suitable means. to the'door amb in the usual manner.

A recess is cut in the bottem portion of the door which is T-shaped at one end thereof as shown bythedotted lines 15in Figure 3. The Tk-shaped portion extends only to the plate 21 hereinafter described. For the remainderof the door thereeess is ofthe width 'shown in Figure 1 andthe height as shown in Figure 2. kThe sidefopening of the recess 15 atfthe hinged, endof the door is closed by the plate 16 which'is secured tothe door by the means 17 of any suitable character.

The swinging' end. of the door is closed by the I :plate 18 whichy is secured by the means 19.

The,v plate 1G has projecting therefrom inwardly into the recess 15 va right angular 20 which can be if The spring retaining memberhas a down-k wardlyv depending portion 21. Passi-ng depend- 23, one endy of which slidesin the guide 24 and theother end of which passes through an aperture 25 in the plate 16.

The actuator 23 has secured'to it a disk member 26 at the endwhich passes through the plate 16 and located on the inside of the plate so as to serve as a stop member for. the helical spring 27 which encircles the actuator 23 and is confined at .its otherl end bythe downwardly extendingmember 21 otth'e spring 'retaining member 20. Y

Into the end of the actuator 23 projecting throughthe slot 25 in the plate 16is a bumper screw 28 which is adjustable in the end of the actuator and can be locked in position by the lock nut 29.

The actuator 23 has pivoted to at two or more link members 30 which are alsopivoted to the scaling member 31. The scaling` member 31 is free to move upwardly and down'- wardly inthe recess 15 and it also carries two spaced upwardly extending supports 32 and 33 located upon opposite sides of the member 21. The members 32 and 33 each serve as supports for the rollers 34 and 35 f Meana respectively. The supports 32 and 33 carry f two rollers eachl one located upon each side` The sealing member preferably carries on thc bottom part thereof a rubber seal 32.

The operation of my invention is as follows: The spring 27 constantly urges the actuator into the right hand position as shown in Figure 2. Upon swinging the door shut the bumper screw 28 will contact the plate 12 upon the door jamb and Will force the actuator 23 towards the left thereby moving the links and depressing the sealing member 3l so as to thoroughly close the space below the 'door l0. In the downward movement of the seal the rollers 34 and 85 guide the sealing member noiselessl-y, to the position desired. This noiseless operation of my sealing means is of extreme importance. There is no possibility of any creaking or other noises.

By means ofthe screw 28 the exten-t Vof movement of the sealing member can be accurately adjusted and when said adjustment has been nia-de further adjustment 'can be eliminated by lockingI the lool; nut 29. It will be' noted that all of the parts are extremely sim-ple andV of sturdy construction.

The return movement of the sealing member is accomplished immediately upon the opening of the door bythe spring member 28 restoring the parts' to their normal position when the door is open.

ySome changes may be made in the construe tion and arrangement `of the invention above set forth Without departing from the real purpose and spirit thereof, and it is the intention to cover by the following claims, any modified forms of structure or use of equivalents, which may be reasonably included Within their scope.v v

I claim:

l. An automatic Weather strip for a door comprising a slidable bar having one end projecting from said door, a sealing member connected to said bar so as to reciprocate transversely thereto, rollers mounted upon said sealing member spaced horizontally With respect to each other and fixed means upon said door cooperating with said rollers for guidingsaid sealing member. Y

2. An automatic Weather strip for a door comprising a slidable bar having oneend' project-ing from the hinged end of said door, a sealing member connected to said bar so as to reciprocate transversely thereto, means carried by said bar for adjusting the movement of said sealing member, rollers carried by said sealing member and fixed means upon said door cooperating With said rollers for guiding said sealing member.

3. An automatic Weather strip for a door `comprising a slidable bar having one end projecting from said door, links carried by said bar, a sealing member connected to said links, rollers carried by said sealing member, fixed' means upon said door cooperating with said rollers to guide said sealing membertransversely to said bar, means urging said bar in a direction so as to raise said sealing means and adjustable means upcn said bar adapted to cooperate with the doorjambto lower said sealing means. f Y
